Drain the water from the tank: to do this, put on the drain valve of the boiler rubber hose, the diameter of which would correspond to the diameter of the valve. Then open the valve and disconnect the heater pipe feeding cold water (pre-seal the tube, the feed from the boiler hot water). Drain: lower the free end of the hose in the sink or the toilet and leave for half an hour.
